Can you believe your eyes ?

Wanted to share something with you that seems too great.

After 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 e6 9.Qf3 c6 10.g5, black must take an important decision that determines the nature of the game. The most obvious choice is 10...Nd5, after which white continues the fierce attack with 11.Bd3 (diagram).

White once again threatens complete destruction, so black has to act accordingly. Let's look at the black options :

a/ 11...Qc7 12.Bxg6
...a1/ 12...hxg6 13.00 (++)
...a2/ 12...fxg6 13.Qg4
......a2a/ 13...Qc8 14.00 (++)
......a2b/ 13...Qd6 14.Ne4 (++)
......a2c/ 13...Qe7 14.00 (++)
......a2d/ 13...Nxc3 14.bxc3 (+)

b/ 11...Qe7 12.Bxg6
...b1/ 12...hxg6 13.00 (++)
...b2/ 12...fxg6 13.Rf1 (++)

c/ 11...f6 12.Nxg6 hxg6 13.Bxg6+ (++)

d/ 11...f5 12.gxf6
...d1/ 12...Qxf6 13.Bxg6+ hxg6 14.00 Qxf3 15.Rxf3 (+=)
...d2/ 12...gxf6 13.Nxg6 hxg6 14.Bxg6 (+)

e/ 11...Nxc3 12.Bxg6
...e1/ 12...Qxd4 13.Qxf7+ Kd8 14.Bf4 (++)
...e1/ 12...Qd5 13.Bxf7+ (++)

f/ 11...Nd7 12.Nxg6
...f1/ 12...hxg6 13.Nxd5
......f1a/ 13...cxd5 14.00 Qe7 15.Bd2 (+)
......f1b/ 13...exd5 14.00 Qe7 15.Bd2 (++)
...f2/ 12...fxg6 13.00 (+)

So it seems black is busted in all lines. But let's have a further look at one particular line, # f1a (diagram).

I had analysed this position in my book "Attack with the Blackmar Diemer" before and concluded it was roughly equal after 15...f5 16.gxf6 gxf6 17.Bxg6+ Kd8 18.Rf2. But now I see that the odd looking 18.Kh1 (diagram) is given as a win by my silicon friend. What a strange move ! But check out the lines yourself, it does win.

So after some very deep analysis, we have to conclude that 10...Nd5 11.Bd3 wins by force ! Can you really believe this ?


  1. Great analysis as always Guido :)

  2. After 18.Kh1 black has 18...Bh6! with only a slight edge for white.

  3. here is a recent game of mine sir inpired by this article:) 11. Bd3! does win:)

    8.Ne5e6 my usual 9th move with this position is to take the white Bishop with my knight but lately my winning percentage is declining so I have to try another battle plan mapped by sir Guido de Bouver
    11.Bd3! “White once again threatens complete destruction, so black has to act accordingly”-guido de bouver. Hmmm? The position is indeed getting messy..
    11… Qe7? Trapping his own bishop? This guy must be punished
    13.O-O this is where the theory ends where whites position is a (++).. so from here on I have to fight the battle on my own
    13…f5?? An obvious blunder! Black is only expecting en passant probably to reposition his knight to f6 but hell no! I’d rather fork his queen, bishop and rook with my next move
    14.Nxg6Qf7? giving me another chance to threaten his queentsk tsk tsk another tempo lost for my opponent
    16.Qh5+ forfeiting the right to castle, disorganizing my opponents pieces and more importantly the king will be stock in the middle.
    17.Nf7+Ke7 here, I started to notice something fishy, the black’s king I think is vulnerable to mating attack starting with
    19.Bf4! black must be careful where he will pull his queen. For example 19…Qc8 20.Nd6 threatening again the queen at the same time the black’s king is being snipe by the whites queen on the next move.. Or 19…Qd7 20. Bd6+ either giving up the blacks queen now or on the next move
    19…Qxc2?? Did my opponent really took the c-pawn? Yes he did! Unluckily the pawn is taboo. My rook can now join the king hunt in the middle of the board.
    20.Rac1 If black doesn’t give up his queen after this move then ,if my own analysis is right, mate in maximum of 6 moves.. for example 20…Qxb2 21.Rc7 Nd7 22.Bd6 Ke8 23. Ne5+ g6 24. Qxg6+ Kd8 25.Rxd7+ Kc8 26.Qe8# or 21.Rc7 Ke8 22.Nd6+ Kd8 23.Rc8+ Kd7orKe7 24.Qe8#
    20… Qe4 probably better was 20…Qa4
    21.Rc7+ Nd7
    23.Ne5+ Kd8
    24Rxd7+ black resigns
